Unified MPLS

• Service and revenue mixes are changing as packet transport requirements explode• The compelling events of Cloud and LTE are driving adoption of intelligent packet based networks to deliver optimal transport• Simplification by protocol reduction, minimal configuration and separation of service from transport operations are all required to realize a cost effective network that can be operated at large scale• Advances in MPLS Technology make a single end to end control, data and management plane feasible for today’s NGNs.• The benefits are simplified operations, reduced skill set for operations, elimination of both protocol translation between domains and scale limitations of legacy technologies.• Leading operators are adopting this approach now to develop a single multiservice network that can improve ROI by the process of “build once, use many times”.© 2010 Cisco and/or its affiliates.

• Packet transport delivers the most efficient and cost effective solution for the exploding packet traffic demands seen in networks today• Infrastructure is converging to get better utilization of fiber and microwave assets, driving the need for virtualization• Compelling events of LTE for mobile and cloud for wireline drives the need for intelligent packet networks• Legacy TDM and ATM transport will persist for many years• For converged packet transport, virtualization and legacy support, the industry has chosen MPLS• Unified MPLS now brings scale enhancements and operational simplification to meet the most demanding operator needs© 2010 Cisco and/or its affiliates.

TDM transport of packets is no longer economically viable, lacks statistical multiplexing which makes it veryChart from Infonetics, Text from DT expensive Full transformation to NGN needs to occur from core to customer Long term vision is critical, this will be the network for the next decade What is the most effective technology choice that will: Minimize CapEx and OpEx? Provide carrier class service delivery? Maximize service agility? Carriers want the deterministic attributes of transport networks with the flexibility of the internet © 2010 Cisco and/or its affiliates. All rights reserved. Cisco Confidential 7
